Abstract

A system (1000) for controlling drive of a crawler vehicle, characterized by having: - a lever (LV); - a hydraulic distributor (HD) for feeding pressurized oil over a feed line (OSL) to a hydraulic actuator (HA); the hydraulic actuator (HA) engaging/releasing a central clutch (CC); - a cable (CBL) having a first end (CBL*) fixed to a rod (RD) of the hydraulic actuator (HA), and a second end (CBL**) connected to the hydraulic distributor (HD) to activate/deactivate it, depending on the position of the rod (RD); and - a main pulley (MPL) integral with the lever (LV), and about which the cable (CBL) is wound.
